This BluePrint, "Techniques for Optimizing Applications: High Performance Computing," is a practical guide to performance optimization of computationally intensive programs on Sun UltraSPARCTM platforms. It is primarily intended for developers of technical or high performance computing (HPC) applications for the SolarisTM Operating Environment (OE), independent software vendor (ISV) developers, noncommercial developers, and end-users of HPC applications to help them better understand how applications utilize system resources.

Authors, Rajat P. Garg and Ilya Sharapov, present information so that it follows logical stages of the process for application development and optimization. They pay special attention to issues related to parallel applications and to using appropriate performance measurement tools. Wherever applicable, sections are illustrated with code examples that show benefits of methods described.

Chapter topics include:

• Application Development on Solaris OE
• Measuring Program Performance
• Basic and Advanced Compiler Optimization
• Linker and Libraries in Performance Optimization
• Source Code and Loop Optimization
• Parallel Processing Models on Solaris OE
• Optimization of Programs Using Compiler Parallelization

There are appendices covering commands that identify system configuration parameters, architecture of UltraSPARC microprocessor and interconnect families, and hardware counter performance metrics.
